Cell board, small cylindrical, multiple cells

1SCxxxx, Cell Boards for multiple, side-by-side 18650 and 26650 cells

Each of these cell boards handles a number of small cylindrical cells in series, mounted side-by-side, in which cells in series are oriented in alternating polarity
(as opposed to a 1SC0100, which handles a single cell).

Matched to industry standard 18650 and 26650 sizes

Mounted on the side of the cells, by their welding tabs

One Cell Board per a number of cells (or sets of multiple cells in parallel)

Simplifies installation and improves reliability (though at the cost of loss of flexibility, compared to single-cell cell boards)

Very thin, components are placed in space between cells: as little as 0.05" is added to battery dimensions

A single communication wire is used between adjacent cells in a bank

These cell boards are done to order and require a BMS master to form a complete BMS

There are 4 possible orientations of the cells, based on which corner of the cell board is the '+' end.
To handle all 4 cases, these cell boards come in 2 versions ("straight" or "mirror"); by a 180° rotation, these two versions can handle all 4 cases.

The arrangement is slightly different between batteries with an even or odd number of cells in series.
